Branchement sur alimentation CA

D A N G E R

Risque d'électrocution Si cet équipement est utilisé à l'extérieur ou dans

des lieux potentiellement humides, un disjoncteur de fuite à la terre

(GFCI/GFI) doit être utilisé pour le branchement de l'équipement à sa

source d'alimentation secteur.

L'appareil de mesure peut être alimenté sur secteur à l'aide d'un

adaptateur d'alimentation universel.

1. Sélectionnez

la fiche d'adaptateur appropriée à la prise électrique dans

le kit adaptateur.

2. Branchez l'adaptateur d'alimentation universel à l'appareil (Figure 2).

3. Branchez l'adaptateur d'alimentation universel à une prise CA

(Figure 3).

4. Allumez l'appareil.
